R. s. SERVIN SLIPPER Filed Jan. 12, 1960 May 3, 1960 INVENTOR. ROBERT $.SERVIN BY M H 324 ATTORNEY snrrnn Application January 12, 1960, Serial No. 2,009

4 Claims. (Cl. 36-9) The present invention relates to a slipper, and more particularly to a stretch-type slipper. For wearing around the house, it is desirable to have a slipper which is soft and comfortable. Also, the slipper should cover the entire foot for warmth, and should snugly fit the foot to hold the slipper on the foot. The appearance of the slipper both on and oil the foot is also an important feature of the slipper.

It has been found that a stretch-type slipper is also very desirable. Such a slipper will fit various size feet so that the slipper need only be made in a few standard sizes to cover the complete range of sizes. In addition, such a stretch slipper is excellent for children since it permits a longer use of the slipper even as the childs feet grow.

It is an object of the present invention to provide a novel slipper.

It is another object of the present invention to provide a novel stretch-type slipper.

It is a further object of the present invention to provide a stretch-type slipper which holds its shape on and off the foot.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

Figure 1 is a side elevational view of the slipper of the present invention.

Figure 2 is a bottom plan view of the slipper of the present invention.

Figure 3 is 'a sectional view taken along line 3-3 of Figure 1.

Referring to the drawings, the slipper of the present invention is generally designated as 10. Slipper comprises a sole 12, an upper 14, and an ankle cuif 16.

As shown in Figure 2, the sole 12 is of a shape to cover the entire bottom of a foot. The sole 12 comprises a layer 18 of an elastic material, such as rubber or foam plastic, and a separate layer 20 of a knitted material covering each side of the elastic layer 18. The knitted layers 20 are of a material that can be stretched longitudinally of the sole 12. The layers 18 and 20 of the sole 12 are secured together around their edges by overlock stitching 22. The elastic layer 18 of the sole 12 is thicker than the knitted layers 20, so that the elastic layer 18 provides a cushion for the foot.

The upper 14 comprises a body of a knitted material having a toe portion 24 and a heel portion 26. The toe portion 24 of the upper 14 extends across the front end of the sole 12, and tapers upwardly into the heel portion 26. The bottom edge 28 of the upper 14 is folded inwardly, and is secured to the upwardly folded edges of the sole 12 by the overlook stitching 22. The heel portion 26 of the upper 14 has an open top edge 30 through which the foot is inserted into the slipper 10, and which United States" Patent O ice fits around the ankle of the foot. The knitted material of the upper 14 includes a plurality of threads 32 of an elastic material, such as rubber, extending along and knitted into the inner surface of the upper 14. The elastic threads 32 extend longitudinally along the upper 14 from the back of the heel portion 26 to the front end of the toe portion 24. Along the top portion of the upper 14, the elastic threads 32 are angled downwardly from the top edge 30 of the upper 14 toward the front end of the toe portion 24. The elastic threads 32 permit the upper 14 to stretch longitudinally of the slipper 10.

The ankle cufi 16 comprises a tubular knitted band of a diameter substantially equal to the diameter of the top edge 30 of the upper 14. The tubular knitted band of the cuif 16 is folded axially upon itself to form two overlapped plies 34 and 36. The free ends 38 and 40 of the overlapped plies 34 and 36 respectively are folded inwardly, and are sewn to the inwardly folded top edge 30 of upper 14 by overlook stitching 42. A band 44 of an elastic material, such as rubber, extends around the free ends 38 and 40 of the plies 34 and 36, and is secured to the free ends 38 and 40 by the stitching 42. The elastic band 44 has suflicient resiliency to permit stretching of the top edge 30 of the upper 14 and the cuff 16, and is of sufiicient thickness so that in its relaxed condition, it will maintain the shape of the top edge 30 of the upper 14 and the cufi 1-6.

In the use of the slipper 10 of the present invention, the elastic band 44 permits stretching of the top edge 30 of the upper 14 and the cuff 16 to permit a foot to be easily inserted into the slipper 10. When a foot is inserted into the slipper 10, the upper 14 and the sole 12 will stretch longitudinally to correspond with the size of the foot. However, the elastic threads 32 in the upper 14, and the elastic layer 18 of the sole 12' hold the slipper 10 snugly around the foot to secure the slipper 10 on the foot, and to provide the slipper 10 with a neat appearance. In addition, the elastic band 44 holds the calf 16 and the top edge 30 of the upper 14 snugly around the ankle which prevents the slipper 10 from sliding oif of the foot, and which adds to the attractive appearance of the slipper. When the slipper 10 is removed from the foot, the elastic threads 32 of the upper 14 and the elastic layer 18 of the sole 12 will return the slipper 10 to its normal size. As previously stated, the elastic band 44 maintains the shape of the culf 16 and the top edge 30 of the upper 14, so that the slipper 10 of the present invention has a neat appearance off of the foot as well as on the foot.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.

I claim:

1. A slipper comprising a sole hoving a relatively fiat elastic material layer covered on each side by a knitted material layer, said sole being of a shape corresponding to the bottom of a foot, van upper of a body of knitted material extending over said sole, said upper having a toe portion covering the front of said sole and a heel portion around the back of said sole, the' heel portion having an open top edge and the toe portion tapering away from the sole to said open top edge of the heel portion, said upper having a bottom edge which extends around and overlaps the edge of said sole, the bottom edge of said upper being sewn to the edge of the sole by a line of overlock stitching, said line of stitching extending through all of the layers of the sole to secure said layers together, the knitted body of said upper in- --c'luding a plurality of ela tom edge of said cuflfiwithin said cuif; said elasticband being secured to the bottom edge of the cuifby the line of stitching joining the cuff to the upper. 1 v
